A radial electric field distribution in free space is given in spherical coordinates as:

where ρ0, a, and b are constants. (a) Determine the volume charge density in the entire region (0 ≤ r ≤ ∞) by the appropriate use of  = ρv .(b) In terms of given parameters, find the total charge, Q, within a sphere of radius r where r > b.
